python 自动获取（打印）代码中的变量的名字字串

import inspect

for line in inspect.getframeinfo(inspect.currentframe().f_back)[3]:
m = re.search(r'\bvarname\s*\(\s*([A-Za-z_][A-Za-z0-9_]*)\s*\)', line)
if m:
return m.group(1)

>>> dsalds_ = 3
>>> varname(dsalds_)
'dsalds_'

>>> a = 'some var'
>>> namestr(a, globals())
['a']

>>> a = 1
>>> b = a
>>> c = 1
>>> d = 1.0
>>> namestr(a, globals())     # 除了globals()，还有 locals()
['a', 'b', 'c', '_24', '_25', '_9', '_27']
